In the drawings the invention is shown embodled 1n`a welt and turn sewing machine i, which is similar in many respects lto the machine shown and described in the Patents, No. 1,076,201, Cctober .21, 1916, and No..

1,108,560, August 25, 191 y The kmachine `is provided with afterV the needle has passed through the work,

a thread measuring arm, arranged to engage 'the thread on' the looper side of .the work between the needle and the work,la kback gage `8Ywhich, as shown, also acts as awelt guide.

\ .atake-up 10, and an auxiliary take-'up 12, all of which lare similar' in construction to the tek corresponding 'parts in the machine of the patents. The machine may alsorbe provided with the usual back rest which is not shown. The channel Vguide'V is in theAf-ormjof a vsmall rollf14 shapedto engage the bottom of the channel or the base of therib on the isole,l and the periphery of which is preferably 'toothed or notched to better grip .the work.

lThe needle, the channel guide and the back gage (welt guide) arefall'recipro'c'ated in the line of kfeed and are timed to impart a continuous feed to thework during the sewing.

'l Theneedle and the channel vguide roll VVare mountedKV on aslide 16 whichis similarin construction tov thefeed slide of the Yabove patents'and is reciprocated by a lcamrfleverv- 18 engaging a feed cam 20 on the cam shaft.

-The needleis secured kin a needle segment. ,whichis pivotally mounted and guided in a Y supporting vplate 22 projecting downward fromthe slidelg The needle `segment is i connected tofan actuating lever24v by alink 26vhz'tving'ball joints at its ends'to permit the movement of theneedle segmentin the line j Bo offeed. The channel guide'rollis carried V on thelowerendof a shaft'28 which is mounted in a .bearing bracketv 30'secured tothe slide 16 and the upperend of the shaft is connected 1 through gearing 32 with a worm 34 on,v .the fcamshaft.. The worm` prevents independent rotation of` the roll and the gearing and Figure iis ak ri la handL ,needlejis undisturbed.V vThe thread finger isl ;.and Fig.k 9'is a sectional view on line 9 of Fig..7.

The swinging arm 36 which carries they back gage (welt guide) is mounted on a supporting plate 38secured ltoa rod n40 mounted Vto slide Vlengthwise in bearings in the mavchine frame and also forming 'the supporting stud onwhich the slide 16 is mounted. The upper end of the arm is supported on a sleeve 42'which'is clamped in a'bearino' inthe plate 38 and'whi'ch surroundsl and slides on a fixed vworm are so proportioned that they will not studk 44. lThe arm is connected by alink v and balljoints to ay back gage slidey 46 vwhich is operated and locked atpropergintervals bymechanismsimilar to that of the above patentsyffThe rod flis reciprocated'by a camv lever 48 the forward end of vwhich is pivoted to a fixed vbracket 50'and the vrear end of 4which carriesa roll engaging the feed cam .20. d The lever is connected to the rodl Vby a pivot stud 52 adjustably securedin a slot in the lever and engaging apivot vblock which fits within a transverse slot in the enlargedend 54 of the-rod." VBy. adjusting the v rstud 52 the travel of the back gage in the line of feed may be varied in accordance with the length of stitch tovbe sewedrand in acchannel guide and .back gage, or Vthe channel guide, `back gagefanfd needle and the needle guidein thefmachine shownare engaging the work and. moving it forward in thelline of feed.` `After the needle has reached its 1re# tractedfposition'the needl'eand channel guide are :back K4fed during which vmovement' the needle'may be advanced toward the work.
